WebDeveloped principally by H. Johnson in the 1950's and A.W.J. Cousins in the 1970's, the Johnson-Cousins range of filters have become the defacto standard for photometry applications. During the 1990's M. Bessel developed the filters to use coloured glasses (absorption filters) to work with CCD detectors. These resulted in relatively thick ... In astronomy, a photometric system is a set of well-defined passbands (or optical filters), with a known sensitivity to incident radiation. The sensitivity usually depends on the optical system, detectors and filters used. For each photometric system a set of primary standard stars is provided. A commonly adopted standardized photometric system is the Johnson-Morgan or UBV photome… did jackson browne have plastic surgery
